Yup thats it, spot on!

I'd only get the mintex drums if they are't that much dearer than the bearings, as the rear drums don't do 'that' much braking. IMHO of course

A bearing puller won't work as there is nowt to grip. I just grind the race down until i'm almost at the stub axle then knock it with a chisel until it cracks. It then slides off.
